BY yzmff/M ATTORNEY United States Patent C 3,073,028 SCRAPER Robert Howard, 435 Fort Washington Ave., New York 33, N.Y. Filed Nov. 7, 1960, Ser. No. 67,760 1 Claim. (Cl. 341-330) My invention is an improvement in scrapers, particularly Scrapers for removing foreign material sticking to surfaces and thus thoroughly cleaning such surfaces and preparing same for washing or other desirable treatment.

The scraper herein set forth is especially useful for freeing culinary vessels from grease, taking off spots of mud or paint from doors and windows, films of ice from windshields of automobiles and in fact any article to which may become soiled or coated and require scraping and cleaning for purposes of restoration.

An important object of my invention is to provide an inexpensive scraper of simple construction comprising a suitable holder or handle with means at one end for gripping an ordinary safety razor blade, having an edge still sharp enough for scraping and securing the blade removably in position for operation as required, yet permitting easy replacement.

Another object is to provide 'a scraper in which the mounting and replacing of the blade can be easily accomplished, without risk of cutting ones fingers. In its preferred form the handle of scraper is made up of two sections pivotally connected together, each having at one end a jaw for engaging the razor blade when the sections are swung apart, and retaining the blade tightly in place when the sections with jaws are actuated to superpose the jaws above each other with the blade firmly gripped between them.

These and other objects and the 'advantages of my invention are all clearly set forth hereinafter; and the novel characteristics of my improved scraper are defined in the appended claim. The drawings illustrate one embodiment of my scraper, but variations in structure may of course be adopted, without deviation from the general design in which the invention resides.

On said drawings, which show said scraper enlarged somewhat:

FIGURE 1 is a plan view of a Scraper according to my invention.

FIGURE 2 is an end elevation partly in section seen from the top of FIGURE 1.

FIGURE 3 is a side view, partly in section, seen from the left of FIGURE 1.

FIGURE 4 is another plan view showing the sections of the handle and the jaws open for insertion or replacement of the blade of the scraper.

FIGURE 5 shows the two jaws in edge view to make clear the special shape and function thereof.

The scraper comprises a handle with two sections 1 and 2 overlying each other, and pivotally connected together, and having at adjacent ends jaws 3 and 4 respectively, between which a safety razor blade can be snugly clamped. Each jaw comprises a flat piece of metal, T- shaped in outline, as indicated in FIGURE 4, the jaws being in transverse position, and the Shanks 6 extending in between the sections 1 and 2. and made fast at their inner ends; which are perforated for the screw 7 that unites the sections but permits them to be turned from ice overlying positions to separate the jaws `somewhat as is apparent in FIGURE 4. The jaw 3 has one end 8 bent over to envelop the terminal edge of the other jaw 4, and the latter jaw 4 has its opposite terminal edge 9 bent to overlap the other end of the jaw 3. Between the portions of the jaws extending from the bent ends 8 and 9 is a narrow space to be lled by the blade 10 between them. The jaws are flexible and nearly in contact, but will yield enough to press on the blade and prevent displacement. The ends of the sections can be rabbeted to seat the jaws, and the Shanks 6 thereof can be seated snugly in longitudinal recesses on the inner faces of the sections to maintain the jaws in place and obviate looseness. The recesses are simply hollowed out seats of the same depth as the thickness of the Shanks 6 and of the same outline; and the parts 1 and 2 are thinned across at their ends adjacent said seats to receive the jaws 3v and 4.

In practice the two sections are swung apart about the pivot 7 (see FIGURE 4), and the razor yblade 10 is then laid between the jaws and its edge at one end is slipped under the doubled-over edge of one jaw, such as the edge 8 of the jaw 3. The unbent edges of the jaws will then overlap slightly as shown in FIGURE 4. The sections are then ready to be turned into overlying relation, as in FIGURE l, and the doubled over edge 9 of the other jaw 4 finally overlies the unbent edge of the jaw 3 and the opposite end of the blade 10, which slips under the edge 9 and is then held fast between the two jaws 3 and 4.

Each jaw has a small triangular tab 11 adjacent the doubled-over end of the jaw and at its inner edge, bent over to lie ush with the bent end to seat the blade 10 properly between the jaws 3 and 4, and the blade is pushed under this tab and the doubled-over edge of the jaw 3, for example, when first inserted between the two jaws. The tabs 11 act as stops for the inner edge of the blade when this `blade is fully seated in the jaws, and the jaws are closed.

As the jaws are forced into closed position, they slide together and move the blade 10 until the opposite end of the blade is under the doubled-over end 9 of the jaw 4. The scraper is then ready for use. One of the sections has a piece of metal 12 rivetted to it between the two sections by a fastening element 13, and this strip projects beyond the edge of the section bearing it and its extremity 14 is bent to present a stop to prevent the other section from overpassing lthe first section when the two sections are moved to carry the jaws 3 and 4 into the positions of FIGURE l. Of course the blade could be laid on the jaw 4 with one end under the edge 9 and adjacent tab 11 and the other jaw 3 moved over to coincide with the jaw 4.

Having described my invention, 'what I believe to be new is:

A scraper comprising a pair of superposed handle members, each of which has a wide portion at one end, said portions being at adjacent ends of said members, a pivot connecting said members in proximity to said adjacent ends, one portion having a projection on one side edge and another projection adjacent the aforesaid projection in proximity to the junction of said one portion with the member of which it is a part, the other portion having a similar projection on its side edge remote from the vaforesaid side edge of the one portion, and a second vprojection Iadjacentits said similar projection in prox- References Cited in the file of this patent UNITED STATES PATENTS Johnson Mar. 12, 1918 Boos Oct. 27, 1931 MacFariane Dec. 5, 1933 Gardner et a1.
